突然想要升级IDEA，留下笔记安装带破解。

新版界面好看，代码提示比老版本更全，感觉接触了新idea一样！！！

2019.3.3 -> 2021.3.3

1、下载安装idea2021.3.3

官网慢,百度找一个云盘下载即可! ==安装最好不要有中文路径!==

官网下载旧版本地址

2、下载破解jar包

放到固定位置，不要有中文目录名称。

本人gitee下载

3、破解

1、进入到bin目录下

# 1、打开文件idea64.exe.vmoptions，添加内容(-javaagent:破解jar放的目录)
-javaagent:E:\exploitSoftWore\IntelliJ IDEA 2021.3.3\ja-netfilter-all\ja-netfilter.jar=jetbrains
# 2、创建idea.vmoptions
-Xms128m
-Xmx1024m
-XX:ReservedCodeCacheSize=512m
-XX:+IgnoreUnrecognizedVMOptions
-XX:+UseG1GC
-XX:SoftRefLRUPolicyMSPerMB=50

-Dkotlinx.coroutines.debug=off
-XX:ErrorFile=$USER_HOME/java_error_in_idea_%p.log
-XX:HeapDumpPath=$USER_HOME/java_error_in_idea.hprof
